The new posters of John Wick 3 show multiple new characters, some foes, and some allies. The "Tick Tock, Mr Wick" ones. And when I go to the comments, everybody appears to be talking about them, their character types and quoting sentences which probably are their "dialogues" from somewhere. Like Asia Kate Dillon, Angelica Huston, Jason Mantzoukas' characters; is there some source from where I can also learn about these characters?
